jobs are queued in an instant.

Higher values are often useful to improve efficiency at the cost of
latency - when fewer processes can do the job over time, starting more and
more is not necessarily going to help.

=item stop => $seconds (default: 10)

When a worker has no jobs to execute it becomes idle. An idle worker that
hasn't executed a job within this amount of time will be stopped, unless
the other parameters say otherwise.

Setting this to a very high value means that workers stay around longer,
even when they have nothing to do, which can be good as they don't have to
be started on the netx load spike again.

Setting this to a lower value can be useful to avoid memory or simply
process table wastage.

Usually, setting this to a time longer than the time between load spikes
is best - if you expect a lot of requests every minute and little work
